Telemark bindings secure only the toe of the boot, allowing the heel to rise freely during turns. This design is fundamental to telemark skiing, where the skier lunges forward with one knee dropped, creating the distinctive telemark turn. Two primary interface standards exist: the traditional 75mm (often called Nordic Norm or duckbill) and the newer NTN (New Telemark Norm). The 75mm standard uses a toe piece that clamps over a duckbill-shaped toe fitting on the boot, often paired with a cable that wraps around the heel for retention and power. NTN eliminates the duckbill in favor of a broader toe interface with side-mounted pins and a heel piece that provides lateral control and a releasable safety mechanism—something most 75mm bindings lack. Telemark bindings range from simple, lightweight cable designs for backcountry use to robust NTN systems that approach alpine binding performance on the descent. The free-heel design means telemark bindings naturally excel at uphill travel without requiring climbing aids or walk modes, making them inherently versatile for touring. However, they require dedicated telemark boots and the commitment to learn a technically demanding turn style.
Telemark skiing occupies a unique space in the skiing world—part alpine, part Nordic, and entirely its own discipline. The binding is the heart of the telemark experience, and understanding the two dominant interface standards is essential for anyone entering this world. The 75mm standard, sometimes called Nordic Norm, has been the backbone of telemark for decades. Boots feature a duckbill-shaped toe that inserts into the binding toe box, with cables wrapping behind the heel to provide retention and driving force. These systems are simple, relatively light, and have a devoted following among backcountry purists. However, most 75mm bindings are non-releasable, meaning they do not release in a fall—a significant safety consideration. Some models, like the Rottefella 7TM, offer release capability, but they are the exception rather than the rule.
The NTN (New Telemark Norm) standard, introduced by Rottefella and adopted by several brands, represents the modern evolution of telemark. NTN bindings use a broader toe interface with spring-loaded side pins and an active heel piece that provides lateral control comparable to alpine bindings. Critically, NTN bindings are fully releasable, addressing the primary safety concern of 75mm systems. The heel piece also provides active engagement that powers the turn, reducing the fatigue associated with cable bindings. The trade-off is weight—NTN systems are heavier than most 75mm setups—and cost. NTN boots are also typically stiffer and more expensive than their 75mm counterparts.
One of the most compelling advantages of telemark bindings is their inherent touring capability. Because the heel is always free, there is no need for a walk mode, climbing aids, or heel risers—the skier simply skins uphill as they would with any touring setup. This makes telemark an elegant one-binding solution for skiers who tour and descend in free-heel style. Some NTN bindings, like the Rottefella Freedom, include a free-touring mode that reduces resistance on the uphill, further enhancing their versatility. For skiers who want the purest backcountry experience with the lightest possible setup, 75mm cable bindings paired with lightweight telemark boots remain popular despite the safety trade-offs.
Choosing between 75mm and NTN comes down to priorities. If safety, lateral control, and downhill performance are paramount, NTN is the clear choice. If weight savings, simplicity, and tradition matter more—and you accept the non-releasable risk—75mm still has merit. It is also worth noting that the telemark market is smaller than alpine, meaning fewer options and less frequent updates. Boot selection is more limited, and finding demo opportunities can be challenging. However, the community is passionate and supportive, and the experience of linking telemark turns on a powder day is, for many, worth every compromise.
